"Pre-releases of the Yakkety Yak are not encouraged for anyone needing a stable system or anyone who is not comfortable running into occasional, even frequent breakage. They are, however, recommended for Ubuntu flavor developers and those who want to help in testing, reporting and fixing bugs as we work towards getting this bos grunniens ready. Beta 1 includes a number of software updates that are ready for wider testing. These images are still under development, so you should expect some bugs," says Set Hallstrom, Ubuntu Studio project lead. He adds: "While these Beta 1 images have been tested and work, except as noted in the release notes, Ubuntu developers are continuing to improve the Yakkety Yak. In particular, once newer daily images are available, system installation bugs identified in the Beta 1 installer should be verified against the current daily image before being reported in Launchpad. Using an obsolete image to re-report bugs that have already been fixed wastes your time and the time of developers who are busy trying to make 16.10 the best Ubuntu release yet. Always ensure your system is up to date before reporting bugs."
So... there may be some bugs then? I was a little unclear on that point.
Anyhow, it's great that the article talks about the silly name of the release, the song it's named after, and about how buggy it is, rather than talking about what sort of new features come with the latest and greatest bugs. I mean, no one gives a crap about boring things like that, right? Or did I miss a link somewhere?
